Description
Metallschläuche, insbesondere solche für höhere Drücke, ferner Kom.pensatoren, Metallfaltenbälge u. dgl. weisen einen stark wellenförmigen Längsschnitt auf. Die durch solche Schläuche hindurchströmende Flüssigkeit bildet an den Metallwindungen Wirbel, die die Strömungsenergie wesentlich. herabsetzen. Aus diesem Grunde können derartige Schläuche, so geeignet sie sonst für bestimmte Zwecke sein mögen, nicht verwendet werden, wenn die Verringerung der Strömungsenergie nicht tragbar ist.Metal hoses, especially those for higher pressures, as well as compensators, Metal bellows and the like have a strongly undulating longitudinal section. the Liquid flowing through such tubes forms windings on the metal Eddy, which the flow energy is essential. reduce. Because of this, you can such hoses, however suitable they may otherwise be for certain purposes, not can be used when the reduction in flow energy is unsustainable.
Hier Abhilfe zu schaffen, ist Sinn und Zweck vorliegender Erfindung, deren charakteristisches Merkmal darin besteht, daß in den Metallspiralschlauch ein beiderseitig, mindestens aber auf der Innenseite glatter Schlauch aus Gummi, Kunststoff o. dgl. eingezogen ist, dessen Wandung hin und wieder mit Löchern versehen ist, die dem durchfließenden Medium einen Durchtritt nach dem zwischen Metallschlauch und eingelegtem Schlauch gelegenen. Raum ermöglicht.To remedy this is the purpose of the present invention, whose characteristic feature is that in the metal spiral hose a hose made of rubber that is smooth on both sides, but at least on the inside, Plastic or the like is drawn in, the wall of which is provided with holes every now and then is that the flowing medium a passage after the between metal hose and inserted hose. Space enables.
Durch die Anbringung dieser Löcher wird erreicht, daß innerhalb des eingezogenen glatten Schlauches der gleiche Druck herrscht wie in dem Zwischenraum zwischen diesem Schlauch und dem Metallschlauch. Der Gesamtdruck der Flüssigkeit wird somit einzig und allein vom Metallschlauch aufgenommen, während der innere glatte Schlauch vollkommen druckentlastet ist.By making these holes it is achieved that within the When the smooth hose is drawn in, the pressure is the same as in the space between this hose and the metal hose. The total pressure of the liquid is thus taken up solely by the metal hose, while the inner smooth hose is completely relieved of pressure.
In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise dargestellt. In den Metallschlauch a ist ein verhältnismäßig dünner glatter Schlauch b aus Gummi oder einem anderen für die jeweiligen Zwecke besonders geeigneten Material eingezogen, der hin und wieder mit Löchern c versehen ist.In the drawing, the subject matter of the invention is in one embodiment for example shown. In the metal hose a is a relatively thin one smooth hose b made of rubber or some other special for the respective purposes suitable material, which is now and then provided with holes c.
